I really liked the character development from all the characters that we get to see. We know their flaws and what they’re working on. Alice and Eileen are complex and I loved reading their emails to each other and the tension that is shown through them. Felix was sassy but pretty honest about his past. Simon was infuriatingly chill, but also very sweet. Eileen is the queen of self sabotage, I felt bad for her but she was also frustrating. And Alice was mysterious and distant. I like the third person limited omniscient perspective we get in the book. There were still some questions at the end but it was mostly satisfying. Highly recommend this one!
